Answer:
The molecular formula for calcium chloride is CaCl2. You know that calcium is a group 2 element and has two valence electrons. You also know that Cl is a group 7 and has 7 valence electrons. Place two dots around calcium and seven dots around two Cl atoms and connect the bonds like this Ca--Cl as shown below.
